This Livelink example shows what a user encounters when they attempt to upload a dll or exe file into a Livelink environment when an Add Version callback has been implemented to prevent this. Because the restriction is implemented as an add version callback, upload of dll or exe files are not only prevented from the web UI. Any operation that requires a version to be added will be restricted. The video explicitly shows the results of trying to do this using the web UI, LAPI or Explorer Pro.

Basic script of video: (1) A text document is added to the environment. (2) The text file is added as a new version to the document. (3) An attempt is made to add notepad.exe as a version. (4) An attempt is made to add a dll as a version. (5) A LAPI program is executed to demonstrate the restriction is enforced for non-web operations. (6) Explorer is used to demonstrate that the restriction is enforced for Explorer clients as well.
